The responsibility of the reduction of the greenhouse gas emissions lies largely with the industrialized world, though the developing countries are likely to be the source of an increasing proportion of future emissions. The projected climate change under various scenarios is likely to have implications on food production, water supply, coastal settlements, forest ecosystems, health, energy security etc. The survey says that the global mean temperature may increase between 1.4 and 5.8 degrees Celsius (C) by 2100. This unprecedented increase is expected to have severe impacts on the global hydrological system, ecosystems, sea level, crop production and related processes. The impact would be particularly severe in the tropical areas, which mainly consist of developing countries, including India. The impact of the GHG emission on the Climate Change is now worsening than we imagined a decade ago. India being the Developing country was not able to adopt any strategy because it is more concerned to the social economic development. The most effective way is to adopt a sustainable development pathway by shifting to the environmentally sustainable technologies and promotion of water conservation, renewable energy, forest conservation and energy efficiency. It's the responsibility of the Indian Scientists to bring up various sustainable methods and technologies which will be accepted environmentally and globally too. Other than talking about socio economic growth, concentration must be dissipated to the introduction of the green technology into the development of the sustainable technologies for the prevailing problem of the Climate change impact.","PeriodicalId":254761,"journal":{"name":"Recent Advances in Space Technology Services and Climate Change 2010 (RSTS & CC-2010)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128017222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Visual Cryptography is the study of mathematical techniques related aspects of Information Security which allows Visual information to be encrypted in such a way that their decryption can be performed by the human visual system, without any complex cryptographic algorithms. This technique represents the secret image by several different shares of binary images. It is hard to perceive any clues about a secret image from individual shares. The secret message is revealed when parts or all of these shares are aligned and stacked together. In this paper we provide an overview of the emerging Visual Cryptography (VC) techniques used in the secure transfer of the thousands of images collected by the satellite which are stored in image library and sent to Google for use on Google Earth and Google maps. The related work is based on the recovering of secret image using a binary logo which is used to represent the ownership of the host image which generate shadows by visual cryptography algorithms. An error correction-coding scheme is also used to create the appropriate shadow. The logo extracted from the half-toned host image identifies the cheating types. Furthermore, the logo recovers the reconstructed image when shadow is being cheated using an image self-verification scheme based on the Rehash technique which rehash the halftone logo for effective self verification of the reconstructed secret image without the need for the trusted third party(TTP).","PeriodicalId":254761,"journal":{"name":"Recent Advances in Space Technology Services and Climate Change 2010 (RSTS & CC-2010)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115959561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Climate changes happen largely from changes to the earth's heat equilibrium. Many factors that manipulated by natural processes and human-made processes. The main factors influencing climate change are extraterrestrial factors, volcanism, earth's surface reflectivity and atmospheric factors. It is the impacts from anthropogenic processes, through the enhanced greenhouse effect, which are likely to be causing contemporary climate change. This in turn could bring about considerable environmental, social and economic disruption if adequate alleviation and variation measures are not implemented. The effectiveness of climate change due to green house effect can be reduced by reducing the surface reflectivity. For this an embedded earth reflection observer is designed. The system is inclusive of flimsy reflection observer, oriented rigidly to a predefined optimized observation angle. It observes the maximum level of transmitted heat from the earth and avoids the effectiveness of climate to shift from its natural state. The designed system maintains the environment temperature not greater than 32° centigrade with ±0.4% of error for a selected sample region during midday irrespective of the day conditions.","PeriodicalId":254761,"journal":{"name":"Recent Advances in Space Technology Services and Climate Change 2010 (RSTS & CC-2010)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122348814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High Definition Television (HDTV), which needs a much larger bandwidth for transmission, coupled with the current demand for hundreds of television channels and the growth in Internet communications through Direct-To-Home (DTH), is resulting in a communications bandwidth shortage. One tool being used to address this problem is Satellite Spot-Beams. To design effective satellite communication system operation at extremely high frequency band (Ka and higher bands), the effect of meteorology is important compared to Ku-band frequencies. Keeping view of the socio-economic and geographic diversities of India, Propagation studies are essential for estimation of attenuation, so that Ka-band satellite links operating in different parts of Indian region can be registered appropriately. This paper analyzes Ka-band satellite communications link availability in various geographical separated spot beams in India using statistical data. This paper proposes 16 spot-beam locations to cover Indian main land. It is based on global rain models integrated with the link budget. The global Crane model and ITU-DAH rain model allow us to examine major system design issues encountered in Ka-band satellite communications that are susceptible to propagation impairments. This system is flexible enough to increase power on specific transmissions when needed to compensate for local weather conditions.","PeriodicalId":254761,"journal":{"name":"Recent Advances in Space Technology Services and Climate Change 2010 (RSTS & CC-2010)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114926172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
